Tribulus terrestris has been part of traditional medicine in India and China for centuries as a treatment for erectile dysfunction, infertility, impotence and low sex drive. Studies conducted in Bulgaria and Russia suggest that tribulus can increase testosterone levels (by increasing luteinizing hormone), DHEA, and estrogen. Preliminary studies in animals show that tribulus increased sexual behavior and pressure within the penis, changes that were attributed to a rise in testosterone. (Gauthaman) In a more recent study, however, men who took tribulus supplements daily for four weeks did not experience any change in their testosterone, androstenedione, or luteinizing hormone levels compared with people who did not take tribulus. (Neychev) Despite the lack of scientific evidence as a natural treatment for erectile dysfunction, some men continue to take tribulus terrestris. The remedy should be taken with the advice of a knowledgeable healthcare provider. Men who have hormone-dependent conditions are advised not to use this remedy. More on Tribulus terrestris
